If you call disp, it will display the text you ordered it to display regardless of whether or not the line ends in a semicolon. For lines that don't call disp or something similar, if a line ends in a semicolon that line will not display its results in the Command Window.

Compare:

a = 1:10; % WILL NOT display anything to the Command Window when executed
b = 1:10 % WILL display the variable to the Command Window when executed
a % WILL display
b; % WILL NOT display

We don't know. You are the one saying to not display it, not us. So if you don't want to display the string 'Matrici caricate:' then simply don't pass it into disp().
